DEVICE FOR RECEIVING BROADBAND SIGNALS BY SEPARATED ANTENNAS Russian patent published in 2002 - IPC

FIELD: radio communications; data reception over communication channels with aid of broadband signals. SUBSTANCE: proposed device that has clock generator, adder, channel maximum and number selection unit, as well as n channels each incorporating two narrow-band filters that functions to divide entire frequency band of signal received into n partial channels connected to first and second antennas, two amplitude detectors with averaging filters, three phase shifters, adder, phase-shifter control unit, counter, two electronic switches, and two threshold units is provided in addition with decoder, second multiplexer, ratio-of-two divider, and also with phase inverter, third amplitude detector, analog-to-digital converter, phase discriminator, and multiplexer introduced in each of n channels. EFFECT: enhanced noise immunity of broadband signal received by separated antennas. 3 dwg
